TEL AVIV – Advisers from Iran’s Revolutionary Guard Units are in the Gaza Strip helping to oversee the firing of long-range rockets by jihadist groups there, according to informed Middle Eastern security officials.

The information comes as the Iranian-backed Islamic Jihad group today claimed responsibility for what it said was missile fire at Tel Aviv. The organization has claimed it fired Iranian Fajr-5 missiles aimed at Tel Aviv.

Earlier today, one rocket launched from the Gaza Strip landed in Rishon Letzion, some seven miles south of Tel Aviv. About three hours later another explosion was heard in the Tel Aviv area.

No casualties were reported in either Tel Aviv or Rishon Leztion.

Since yesterday, Israel’s Iron Dome anti-missile defense system has intercepted 105 rockets, while 274 rockets have struck Israel, mostly in cities near the Gaza Strip.

The escalation began last week, when Hamas fired more than 120 rockets and mortars into Israel in a four-day period.

GAZA — Masked gunmen in Gaza summarily executed a man here on Friday as a suspected collaborator with Israel on the third day of its deadly aerial bombardments, shooting him multiple times and leaving his body beneath a billboard featuring a Hamas fighter holding a rocket.

The executed man, identified as Ashraf Ouaida, had a poster hung around his neck accusing him of cooperating with the Israelis in the killing of 15 Palestinian leaders.

Wael Mohammed, a taxi driver who was standing on the steps of the Aman Mosque in the Sheikh Radwan neighborhood of Gaza City, said that around 11:45 a.m. he saw a Jeep pull up on Al Jalla Street, from which two masked men dragged Mr. Ouaida to the dirt circle under the Hamas billboard.

“They took him out from the Jeep with his hands cuffed behind his back, they pushed him under the poster and fired three gunshots at his head from the back,” Mr. Mohammed said. “He was still alive. Then they set his cuffs free and turned him upside down and fired on him again.”

In history, there was something called the ‘Punic Wars’. They were about the city of Carthage, close to today’s Tunis. After the third war, the city was annihilated, because a coexistence with Rome had proven impossible. I wonder if Gaza can’t be compared to Carthage? They could give the population several days to move, before turning it into a pile of rubble.

Michael Rome also plowed a lot of salt into the ground so it wouldn’t grow anything, then years later had to work hard to remove the salt so they could grow wheat on the same land. That area was the breadbasket of Rome and was quite fertile until the Arabs brought in the goats.
